概要
- 論文の詳細を見る
We have investigated universal conductance fluctuations (UCF) in a narrow channel of two-dimensional electron gas subjected to a gradient magnetic field with a vanishing average, generated from a cobalt strip deposited along the center line of the channel. We find that the fluctuation amplitude ΔG tends to be a larger value in the low-temperature limit and the characteristic field B_c is less temperature sensitive, compared with those for UCF in a uniform magnetic field.
